Sparse implicitisation reduces geometric operations on curves and (hyper)surfaces to manipulating an interpolation matrix. The method relies on a point sample on the object, given in two alternative representations:<br \/>\n<em>Parameterised\u00a0objects:<\/em> Sparse implicitisation by interpolation has been studied in a series of articles by the supervisor and his team, e.g. [<a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S0010448512002138\" target=\"_blank\">1<\/a>,<a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S1524070315000260\" target=\"_blank\">2<\/a>]. This PhD advances the state-of-the-art in one or more of the following ways: (i) numerically improve the definition of the implicit equation, (ii) handle objects of\u00a0higher codimension, namely space curves, (iii) exploit information about the normals to the curve\/surface. In collaboration with SINTEF (and INRIA) we juxtapose the method to other approaches, including those developed in ESR4, ESR8.<br \/>\n<em>Point clouds:<\/em> Modern technology, such as scanners, is increasingly leading CAD developers to represent objects as point clouds, which offer flexibility for web applications. RISC-Software (also Missler) studies point samples defining solids swept\u00a0along a path, and the resulting triangular mesh. Our goal is to reconstruct approximate boundary\u00a0surfaces by point sampling with feature-aware distribution, segmenting the mesh to a graph of implicit, low-degree patches based on surface fitting, and recovering geometric features\u00a0like edges or corners, for NC tool verification (cf. ESR2).<\/p>\n<p>The project will take place at ATHENA RC under at the <a href=\"http:\/\/erga.di.uoa.gr\" target=\"_blank\">ErGA Lab<\/a>. The PhD will be awarded by the Dept. of Informatics and Telecoms of the University of Athens.<\/p>\n<p><strong>Secondments<\/strong> are planned at\u00a0SINTEF (Oslo, Norway)  and at industrial partner RISC-Software (Linz, Austria).<\/p>\n<h4> Publications<\/h4>\n<ul>\n<li>I.Z.
